1. Welcome to Week Eleven Fungi
Life Science
Week 11
Mrs. Rubright
Fungi are plant-like, but they are not _____________ or _________________. They are not even ___________.
angiosperms
flowerless plants
plants

2. Fungi – A type of grouping or classification
They are not a plant.
They grow in damp dark places.
They feed on living or dead things.
The examples include mushrooms, molds, and yeast.

3. Fungi – a diverse category
Fungi may look like:
Bright miniature umbrellas
Waxy blobs
Green fuzz
White flowers
Purple sponges
Red cups

4. Fungi – Structure
Fungi are nonvascular organisms that don’t have chlorophyll
They can’t photosynthesize to make their own food.
Fungi are heterotrophs, feeding off other organisms
Fungi are saprophytes, organisms that absorb their food from living and nonliving things

5. Fungi – Structure
Hyphae are threadlike filaments that produce enzymes to break down organic material and weave together to form different kinds of fungi.
Mycelium is the large mass of hyphae that forms the growing structure.
Unlike plant and animal cells, hyphae are a continuous thread that contains many nuclei that aren’t divided by cell walls.

6. Mushroom –Type of Fungi
The cap part is called the fruiting bodies. This houses gills and spores.
Spores are small reproductive cells that can develop into an adult without fusing with other cells
When ready, the spores release and scatter. If the land has suitable soil, they grow new mushrooms.

7. Mold and Mildew These usually do not produce fruiting bodies.
They grow in warm, damp, dark places, feeding on living or dead things such as paper and wood.
Mildew - looks like a white power or black patches.
It grows in damp places – like a bathroom.
Mold – shapeless, fuzzy fungi with cottony myceliums.
Mold spores give different kinds of mold different colors
This may be found as small blue spots or green furry spots on old bread.
Hyphae of bread mold
Hyphae of powdery mildew on the surface of a grape leaf

8. Fungi and the World Many plants could not survive without fungi.
Helpful fungi grow on 80% of plants
Some send their hyphae into the roots of plants
This helpful interaction between fungi and tree roots is called a mycorrhizal relationship
Lichens also work together with other plants.
Lichens are made of 2 different organisms: fungi and algae
This interaction is called mutualism
Fungi provides water and nutrients. The algae makes food through photosynthesis and shares it with the fungi.
This allows fungi and algae to live in harsh climates

9. Useful kinds of Fungi Yeast is used to make bread.
Penicillin is a type of mold used to cure various diseases.
Mold is also used to make certain cheeses.

10. Harmful kinds of Fungi Many mushrooms are poisons.
Certain molds can kill plants.
Fungi can cause skin diseases on humans. Some examples include ringworms and athlete’s foot.

11. Question 14 What am I called?
I am not a plant.
I grow in damp dark places.
I feed on living or dead things.
I could be mushrooms, molds or yeast.
I am:
_________
Fungi

12. Question 15 What am I called?
I am a type of fungus.
I have a cap part that is called the fruiting body. It houses gills and spores.
When my spores are ready, I release and scatter them. If the land has suitable soil, they grow new mushrooms.
I am a:
____________
Mushroom

13. Question 16 What are our names?
We are not plants.
We do not produce fruiting bodies.
We grow in warm, damp, dark places, feeding on living or dead things such as paper and wood.
We are
